Ruthenium, an Ack-like searcher

Ruthenium is an attempt to implement the well-known Perl tool ack in Rust.

When finished, it is supposed to show the strengths of Rust, for example simple and efficient concurrency without locks, and speed comparable with C programs, in this case the implementation called ag or the_silver_searcher.

How to build

Use cargo build --release. target/release/ru is the binary.

How to use

The resulting binary is linked statically against Rust dependencies, so it can be copied into a bin directory and used.

Command line

Command-line options are designed to be mostly compatible with Ag. There are probably small differences, especially in the handling of ignore files.

Regex engines

Currently, the regex engine can be selected to be either Andrew Gallant's Rust implementation regex (the default) or PCRE (requires libpcre and its headers to be installed). Select the latter with the Cargo feature flag pcre.
